Remote monitoring system of vital signs for triage and detection of anomalous patient states in the emergency room

The monitoring of patient's vital signs is a crucial part of triage in the emergency room in order to determine the severity of their state. This paper describes the development of a remote and constant monitoring system of vital signs in the emergency room as support to the patient triage process. The system keeps track of the patient's state for the proper treatment of emergency situations. The monitoring is accomplished through a bracelet that allows to measure body temperature, pulse and respiratory rate by processing the signals generated by a temperature sensor and a photoplethysmograph. Signals are transmitted in real time to a computer system that enables to visualize vital sign information and generates alerts if an anomalous situation is detected.
